To all whom it may concern:

Be it known that 1, WILLI M a citizen of the United States residing at Hartford, in the county of artford and State of Connecticut, have invented certain new and useful Improvements in Power- Transferring Mechanism, of which the following is a specification.

This invention relates :tofpower-transfer ring mechanism, the '0b]8Ct of the invention being to provlde means of thisycharacter which is simple in construction by which hlgh speeds can be obtained, r1ct1on. reduced to a min1mum,wh1ch is compact, and

the parts of which can bewassembled forpropcr action without undue preciseness in the constructiono-f one or more ofthem.

Power-transferring mechanism involving my invention, can be employed with advancordance with the invention, said mechanism being utilized to rotate a chuck to which a drill or other suitable tool may be connected.

In said drawing the numeral 2 denotes a column or upright, to the upper end of which is clamped one extremity of an overhanging arm or bracket as 3, the power transferring means being sustained by said arm at its other extremity. Clamped at the forward end of said bracket is the stud 4: which as will be understood is not rotary. Threaded into the upperside of. the free end of the bracket is an oil cup 5 which delivers its oil into the bore 6 extending longitudinally of the stud 4. The upper end of the stud as will be understood extends short of the top of the arm 3, the upper end of the bore opening into the upper surface of the stud. The bore or duct extends part of the length of the stud and leading from it near its closed inner end isthe lateral port 7 to supply lubricant to a sleeve as 8. Said sleeve 8 is externally of two diameters, the

portion 9 of greater diameter being in the ram,

form practically of an inverted cylindrical: cup. The reduced or. shank portion 10, of

the sleeve 8 receives around it a suitable driving member such as the pulley 11, the two, being suitably connected for, rotation, for. instance by pinning, the screw 12 being shown for this purpose. Said screw is tapped into the stepped on conepulley 11 a and its pointed end enters a correspondingly shaped socket insthe reduced portion 10.. o

By forming the sleeve of two external diam: eters,-I.produce at the junction of the two portions 9 and-10 thereof, an external annular shoulder 13 which presents a suitable bearing for the pulley 11. As shownythe upper ends of the sleeve on hollow spindle member 8 and the pulley are flush and out of contact with the adjacent end of the over..- hanging arm or bracket 3.

The chuck 14 may be removably connected 16',

with the threadedstud 15 of the cap the bottom of which preferably fits solidly against the outer edge of the cup-like portion 9. The flange l7 vof said cap16 is. in threaded engagement with the outer end of the cup-like part 9.' The bottom of said cap 16 presents a suitable support for the disk 18 presenting one member of an anti-friction bearing, said anti-friction bearing member 18 being hardened and having on its inner side the pocket 19 to receive an anti-friction element such as the ball 20. The other element of the bearing consists of a hardened disk 21 which freely fits the cup-like part 9 and which engages the ball 20. The disk or bearing member 18 closely fits the cup 9.

The stud 4 has at its lower end the circular foot'22 which also freely fits the cup 9,

and this foot isconnected with the hardened bearing member in some suitable manner, for instance, by a tongue or key portion 24: on the bearing member 21 which enters a notch or groove in the adjacent surface of the foot 22 which provides a simple means for preventing the bearing member 21 from turnconstrution flis advantageous in that ear is automatically taken up or compensated for. Beside this no great aecuracyis required iii'forfliifigthe chamber ofthe' cu 9 exceptthatthis ehsmbershduld'be of a depth slightly greater than the combineddepth ofthe parts Within it. It Willbe clear that thrust of the springs 26 in the Construction shown, is upward, these springs findinga" bearingagainst a statibnary part of the stud 4:, so that their constant efiect is w elevate the sleeve 8, not only to take up the Wear but t6 EiEGiIi'ateIy positidn' the -bearing parts in th. cup 9; riijt'withstaildihg the difference in 9th betw en said 'ha'inber ens the *parts therein to whifih lphave alluded! 1 #It' will be iioted that the stationary stud-*4 iswftwodismeters; theshank e'f theystud as fot22'thereef: Itwill-also'he observedthat internally-the sleeve ei-shell is (if two:- di
